The force of interaction in the universe that is responsible for chemical reactions, and reactions between light and matter.

The force of interaction in the universe that is responsible for chemical reactions, and reactions between light and matter is the electromagnetic force.

Here are the steps to understand this:

1. There are four fundamental forces in the universe: gravitational, electromagnetic, strong nuclear, and weak nuclear.

2. The gravitational force is responsible for the attraction between objects with mass, like planets and stars. It's not involved in chemical reactions or interactions between light and matter.

3. The strong nuclear force holds the nucleus of an atom together. It's stronger than the electromagnetic force but operates only at very short distances, inside the nucleus of an atom. It doesn't cause chemical reactions or interactions between light and matter.

4. The weak nuclear force is responsible for radioactive decay and nuclear fission. It doesn't cause chemical reactions or interactions between light and matter.

5. The electromagnetic force is responsible for the attraction and repulsion between charged particles. It operates over infinite distances and is responsible for electricity, magnetism, and light. It's the force that holds electrons in their orbits around the nucleus of an atom, and therefore, it's responsible for chemical reactions. It's also responsible for the interaction between light (which is an electromagnetic wave) and matter.
